No, the modules conflict.

are compatible with standard linux bridges, but OVS adds more
features. You may want to discuss the finer points of this with the
ovs-discuss mailing list.
XenServer 5.6 FP1 Admin Guide (p.72) defines "network", which is one type of server-side software objects which represent networking entities.
"A network, which is a virtual Ethernet switch on a XenServer host. Network objects have a name and
description, a globally unique UUID, and the collection of VIFs and PIFs connected to them."
OK, I will discuss with ovs-discuss mailing list.

as I know). My guess is that it doesn't come as a standalone product,
but instead is included with the commercial (non-free) version of
Citrix XenServer. You could ask in the Citrix XenServer forums for

it vSwitch Controller can be downloaded as a .xva file after log in My Citrix.
I've donwloaded and imported as VM.
However, it is started with errors:
"This VM cannot be started, as its network interfaces could not be connected. One of the NICs is in use elsewhere."
From XenCenter, the field "Active" of any attached network is "No", but those of other VMs are "Yes".
Maybe I do not meet requirements of vSwitch Controller, and will try more.
Or maybe it detects that the host is XCP and prevents from starting on free edition of XenServer

commercial controller to XCP, but as of now I don't think there is any
support for that.
Right. At this point on XCP you are probably forced to roll your own

controller solution. You should discuss this on the nox, openflow, and
open vSwitch mailing lists for what your options are.
I am trying Beacon, which a Java-based OpenFlow controller, because my developing language is Java.
I don't actually see the vSwitch controller on there as an item, but I
think we should sort this point out and add it.
There is a feature "Distributed virtual switching management tool" at that wiki page.
I think it is vSwitch Controller.
